If I wanted to write a program that could be run for generations to come I would target a specific piece of hardware of significant historical importance such as the 6502 (for example.) Not only are there already many emulators for it, and not only is it fairly easy to write an new emulator for such a straight-forward system (unlike, say a PS3, which is very difficult to emulate), but because of its historical importance it is likely emulators will continue to be written and maintained for a very long time. Even if my program would not be of historical importance itself, but by targeting the same hardware it would piggyback on other preservation efforts.
